Your returning your drives to Micropolis as soon as they have a single
media related failure :-(. I suggest you turn on AWRE and ARRE and then
run a dd command to attempt to remap the block automagically:
scsi -f /dev/rsd0 -m 1 -P 3 -e
# Make the above changes with your editor, save and exit
# Now scan the disk, hopefully it will be able to do retries and
# recover the bad block...
dd if=/dev/rsd0 of=/dev/null bs=32768
Your drive life will probably go up by an order of magnitude...

What model drive are you using??
